Slide

This article provides a series of examples that demonstrate how to work with slides using Aspose.Slides for PHP via Java. You’ll learn how to add, access, clone, reorder, and remove slides using the Presentation class.

Each example below includes a brief explanation followed by a code snippet in PHP.

Add a Slide

To add a new slide, you must first select a layout. In this example, we use the Blank layout and add an empty slide to the presentation.

function addSlide() {
    $presentation = new Presentation();
    try {
        // Each slide is based on a layout, which itself is based on a master slide.
        // Use the Blank layout to create a new slide.
        $blankLayout = $presentation->getLayoutSlides()->getByType(SlideLayoutType::Blank);

        // Add a new empty slide using the selected layout.
        $presentation->getSlides()->addEmptySlide($blankLayout);

        $presentation->save("slide.pptx", SaveFormat::Pptx);
    } finally {
        $presentation->dispose();
    }
}

💡 Tip: Each slide layout is derived from a master slide, which defines the overall design and placeholder structure. The image below illustrates how master slides and their associated layouts are organized in PowerPoint.

Access Slides by Index

You can access slides using their index.

function accessSlide() {
    $presentation = new Presentation("slide.pptx");
    try {
        // Access a slide by index.
        $firstSlide = $presentation->getSlides()->get_Item(0);
    } finally {
        $presentation->dispose();
    }
}

Clone a Slide

This example demonstrates how to clone an existing slide. The cloned slide is automatically added to the end of the slide collection.

function cloneSlide() {
    // By default, the presentation contains one empty slide.
    $presentation = new Presentation();
    try {
        $slide = $presentation->getSlides()->get_Item(0);

        // Clone the first slide; it will be added at the end of the presentation.
        $clonedSlide = $presentation->getSlides()->addClone($slide);

        // The cloned slide index is 1 (second slide in the presentation).
        $clonedSlideIndex = $presentation->getSlides()->indexOf($clonedSlide);

        $presentation->save("slide_cloned.pptx", SaveFormat::Pptx);
    } finally {
        $presentation->dispose();
    }
}

Reorder Slides

You can change the order of slides by moving one to a new index. In this case, we move a slide to the first position.

function reorderSlide() {
    $presentation = new Presentation("slide.pptx");
    try {
        $slide = $presentation->getSlides()->get_Item(1);

        // Move the slide to the first position (others shift down).
        $presentation->getSlides()->reorder(0, $slide);

        $presentation->save("slide_reordered.pptx", SaveFormat::Pptx);
    } finally {
        $presentation->dispose();
    }
}

Remove a Slide

To remove a slide, simply reference it and call remove. This example removes slides by index and by reference.

function removeSlide() {
    $presentation = new Presentation("slide.pptx");
    try {
        // Remove a slide by index.
        $presentation->getSlides()->removeAt(0);

        // Remove a slide by reference.
        $slide = $presentation->getSlides()->get_Item(0);
        $presentation->getSlides()->remove($slide);

        $presentation->save("slides_removed.pptx", SaveFormat::Pptx);
    } finally {
        $presentation->dispose();
    }
}
